3. The digits are secured to the
inside of the panel with fixed
machine screws, spacers, and
push nuts. Remove the nuts
and lift the digit off the
standoff screws. (The push
nuts can be removed in several
ways, but Daktronics
recommends using a
9 /
32
" nut
driver.)
4. Position a new digit over the
screws and tighten the nuts.
5. Reconnect the power/signal
connector.
Note: This is a keyed
connector it will attach in one
way only. Do not attempt to
force the connection!
6. Close and secure the digit
panel and test the display.
Replacing a Digit Segment
When a digit segment malfunctions, in most cases it is necessary to just replace that
segment board. The larger digits (24", 36", 48"), as shown in
Figure 16, are made up
of LED segments. As with smaller digits, the digit segment circuit boards are
mounted to the back of the digit panel. Do not attempt to remove individual LEDs.
To remove a digit segment, follow these steps:
1. Open the digit panel as described above.

2. Disconnect the 2-pin power/signal
connector from the back of the
individual segment. Release the
connector by squeezing together the
locking tabs as you pull the connector
free.
3. The individual segments are secured to
the inside of the panel with fixed
machine screws, spacers, and push nuts.
Remove the nuts and lift the segment
off the standoff screws.
4. Position a new segment over the screws
and tighten the nuts.
5. Reconnect the power/signal connector.
Note: This is a keyed connector it will attach in one way only. Do not
attempt to force the connection!
6. Close and secure the digit panel and test the display.
Replace a malfunctioning colon, decimal, or indicator assembly in the same manner.
